## What is Baseline?

Your normal is the reference.

Baseline brings sleep, heart-rate variability (HRV), resting heart rate, activity and supported temperature signals into one personal view. Instead of comparing you with a population average, it learns your recent range and shows when today meaningfully differs from it.

SEE THE TWO-SECOND ANSWER

Readiness, recovery, stress and training signals help you decide whether today suits a hard session, an easier effort or more recovery. Every score shows its calibration state, so an early estimate is never presented as final.

UNDERSTAND THE EVIDENCE

Explore your sleep, HRV, resting heart rate, steps and workouts over time. Open any metric to see its history and how it compares with your own rolling baseline.

BRING THE WEARABLE YOU ALREADY USE

Connect supported Polar devices and QRing-compatible smart rings directly over Bluetooth. Baseline Cloud subscribers can also import approved history from Apple Health, including compatible data written by Apple Watch, Garmin, Oura, WHOOP, Fitbit, COROS, Polar Flow and other apps.

LOCAL FIRST, CLOUD OPTIONAL

Your iPhone owns the primary record. Baseline Cloud is an optional auto-renewable subscription that adds Apple Health import, encrypted off-device copy, unlimited cloud history, cloud AI briefings and chat, and support for multiple direct devices. Cloud copy and cloud AI each remain under your control.

BUILT FOR PERSONAL PATTERNS

Tag days and activities to discover associations in your own history. Share an aggregate pattern card after reviewing exactly what it contains—without raw samples, dates, device identifiers or account details.

Baseline provides personal health and fitness insights. Its scores and signals are heuristic and are not medical advice, diagnosis or treatment.

## Version history (last 2 releases)

### 1.0.2 — 2026-09-03

Baseline 1.0.2 makes recovery data more reliable online and offline. Ring timestamps, sleep stages, HRV lineages, and Apple Health values now stay coherent; missing readiness and illness-watch signals fail safe instead of recommending hard training. The iPhone remains the local source of truth when Cloud is unavailable, sync retries are bounded, and Insights shows a useful offline summary. You can also share privacy-reviewed personal pattern cards without raw samples, dates, device details, or account identifiers.

### 1.0.1 — 2026-09-02

No release notes.
